SHARPENING DEVICE FOR SKATES, &c.

Specification of Letters Patent.

Patented Feb. 25, 1908.

Application filed September 3. 1907- Serial No. 391.232-

T all whom it may concern:

Be it known that I, Louis J MooRMAN, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sharpening Devices for Skates, &c., of which the following is a full,

clear, and exact description.

vice for skates, and edged articles of household economy, etc., and for holding and directing the movement of the same while being sharpened.

The object of my invention is to provide a sharpening element which considering the work it is designed to accomplish is as small as possible;twhich can be easily adjusted to present different parts of its surface to the work so that it will not wear out easily, and which can be readily replaced when it has outlived its usefulness.

It is also an object of my invention to provide a holder for said sharpening element that can be stamped out of one piece of sheet metal and very easily and economically reduced to proper shape; which can be conveniently grasped and held without discomfort to the user; and which can be utilized for sharpening a great variety of articles as well as for cleaning knives, without requiring alteration or readjustment of parts, and can withal be carried about the person. This I accomplish by the means hereinafter fully described, and as more particularly pointed out in the claims.

In the drawings :Figure 1, is a side view of my invention. Fig. 2 is a similar view of the opposite side thereof. Fig. 3 is a plan view of the top of the same. Fig. 4 is an end view. Fig. 5 is a transverse section taken on dotted line 55, Fig. 3. Fig. 6 is anend view showing a modified construction of my improved sharpener. of the templet from which the holder is made.

In the drawings, A represents a cylindrical shaped sharpening stone or file which may be of any suitable material either natural or artificial, although I prefer an emery composition pressed into the desired shape with a suitable spindle at extending centrally through the same. The ends of this spindle form journals and one of them is extended beyond its bearings and bent to provide a crank. b with which to revolve the stone, although this can be dispensed with if desired.

The stone A is housed within a suitable I the stone. My lnvention relates to a sharpening de-,

Fig. 7 is a plan view holder, which consists of a partly cylindrical case B within which the stone revolves, and which is provided with outwardly flanged edgesthat form parallel lips c, 0, between which the runner of the skate is placed when it is desired to sharpen the same by rubbing its edge longitudinally back and forth against At one end of one lip c and at the opposite end of the other, said lips are rovided with transversely, projecting lugs (I, C,

against which the fingers brace when the holder is held in certain positions. The end of each lip opposite lug C is extended to form guards (Z for the fingers.

In order to provide bearings for the spindle a the end edges of the case'B are, about opposite the runway between lips c, 0, provided with hearing lugs D, D, that lap down in front of the ends of the stone. These lugs may be so disposed and the bearing openings therein so located that the axis of the sharpening stone will coincide with the axis of the cylindrical case B, but I prefer to so locate and dispose of said lugs and bearing openings therein that the axis of said stone will be slightly oblique to the axis of the case and cross the same at about its center of length. This arrangement not only allows of the use of a stone of less diameter, but presents a convex shar ening surface to the edge of the runner of said edge the same concavity as though a stone of much greater diameter than the case was employed. If desired the spindle a can be dispensed with, and the ends of the bearing lugs D turned in towards and enter concentric openings made to receive the same in the ends of the stone substantially as shown in Fig. 1 of the drawings.

Besides its principal function of sharpening skates, my invention can be employed for shar ening knives, scissors, needles, etc. To do tfiat I provide the cylindrical case or portion of the holder with C-shaped opening E, the tongue 6 thereof outlining the concave portion of said opening having its extremity made broader to make a head and a narrow neck therefor. When it is desired to sharpen a knife-blade, the sharp edge is inserted under the tongue and moved transversely back and forth against the stone, the narrow neck of the tongue preventing the sharpened edge of the knife from being injured by the edges of said tongue. I prefer to locate openings E as near one of the lips as practicable and about the center of length the skate which gives of the cylindrical case of the holder. Between the same and one end of the case I make a narrow transverse slot F through which the points of needles or other sharp pointed instruments or tools can be inserted and sharpened upon the stone. Between the o ening'E and the opposite end of the case Fprovide a comparatively short slot G which preferably extends in a spiral direction. The edges of the scissors-blades are sharpened in this slot, and in order to enable the same to be held in the proper position to prevent the edge of the blade from contacting with the ends of the slot I have provided one longitudinal edge, preferably adjacent to opening E with an advanced portion g as shown.

In the side of the holder opposite that occupied principally by opening E and slots F and G, I have made two comparatively long longitudinal slots H and I. These slots are located such a distance apart that the strip of metal between them is slightly elastic. When it is desired to clean a knife-blade, the latter is inserted transversely into one and out of the other slot, and is held so tight against the stone that by drawing it longitudinally back and forth several times it is guickly cleaned. I do not wish to be conned to the parallel arrangement of slots H and I as they can be dispensed with and disposed at a slight angle to each other if deemed necessary.

In Fig. 7 of the drawings I show a templet consisting of a single piece of sheet metal showing all the parts of my invention as they appear before being bent into shape, and demonstrating the ease and inexpensiveness of its construction. Of course the holder could be made of several pieces of metal properly assembled, but I prefer making the same as described. i
